INDIANAPOLIS -- On Wednesday, Indiana's Building Safety Commission unanimously passed new regulations to help prevent another state fair tragedy.

Temporary rigging like lights and sound must now pass a tougher design and inspection standards.

There also needs to be an evacuation plan in place, and someone appointed to oversee it.

"It's a longer process for an event planner, because the state requires a 14-day notice for plan review," said David Hannum, the Building Safety Chairman.

Safety officials said concert-goers may complain about the new rules, because now they won't be able to get as close as to the stage.

The changes take effect on Thursday.
